[0003] After retrieval, the Chinese Patent Publication No. CN212273413U discloses a municipal pipeline rainwater recovery and utilization pipeline sealing device. A pipeline water blocking airbag is placed on the right side of the municipal pipeline main body, and an inflatable pipe joint is installed on the right end of the pipeline water blocking airbag. An iron plate is installed on the right end of the pipe water blocking airbag, and a clamping plate is arranged on the right side of the iron plate. A magnet block is installed inside the clamping plate. A connecting rod is fixed on the right side of the clamping plate. A connecting plate is installed on the right side of the connecting rod. A fixed floor is installed, and a sleeve is installed on the right end of the fixed bottom plate. An installation head is installed inside the sleeve, and a telescopic rod is connected to the right side of the installation head. inconvenient problem

[0004] Considering that the inner diameters of the pipelines that need to be closed for testing or maintenance are different in size, during the use of the existing municipal pipeline rainwater recycling pipeline sealing device, it is necessary to replace the airbags of different sizes for pipelines with different inner diameters, which makes its scope of application very limited. And less flexibility when using
